Enzymes for Alcohol & Brewing

Glucoamylase FERZYME PG

Made from Non-GMO strains of Aspergillus niger, enables greater conversion rate of liquefied starch to glucose with less processing cost.

Product Specifications

DESCRIPTION

Glucoamylase FERZYME PG is made from non-genetic modified strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. FERZYME PG can catalyze the release of glucose units from the non-reducing ends of soluble dextrins by hydrolyzing both linear (1,4-alpha-D) and branch (1,6-alpha-D) glucosidic linkages.

FERZYME PG is a food grade enzyme designed for saccharification in brewing industry such as potable alcohol production and production of highly attenuated low carbohydrate beers and improved attenuation.

BENEFITS

Use of FERZYME PG greatly benefits the brewing process as follows:

■ Higher conversion rate from liquefied starch to glucose

■ Considerably improves raw material utilization

■ Faster fermentation efficacy

■ Lower processing cost
